I used this tool on cardstock paper, along with the self-healing mat, to cut small letters/words & designs out to use inside luminary bags and it has been perfect for my needs. It curves and does straight lines. I was able to use it from the beginning, but do find with practice, I am getting faster and figuring out ways to hold it that work best for me. Delivery was also prompt. Not sure what to expect when I ordered it, but I have been pleasantly surprised and happy with the results.
